New and in search of help

Hello... I am new to this and in setting up my page, I seem to be encountering some problems. As I run through the categories (i.e. widgets, picture, categories, etc...), I have picked what I would like, but they don't seem to show up on the page. Just the default items appear. I am using the Quentin theme. The URL is radiopromoguy.wordpress.com. I haven't written anything yet... just trying to get the basic set-up. Any help would be appreciated.

Thank you for the help! I knew it had to be something simple! I still can't get my picture to post... maybe the theme doesn't support it? I also changed the URL. It's http://bloggeddown1.wordpress.com/
